This work examines the private relationships among modern American presidents, including Jack Kennedy and “Ike” Eisenhower’s rivalry, Jerry Ford and Jimmy Carter’s unexpected alliance, and the deep sense of competition between Bill Clinton and Barack Obama. A Q&A and book signing follow the program.
